shape of the male sepals and of the cup of the corolla, the shape of the bract in the
female infloreseaace, and the number, size, and degree of hairiness of the flowers,
are all extremely variable. The shape of the sepal of the female flower, we thought,
might flffprd characters of importance, but it ma^ be seen to vary to a great extent
even in the different flowers in the axil of the same bract, not only in size, but in
shape, being sometimes spathulate obovate, sometimes broader than long, and quite
entire, at other times emarginate, or even bipartite to the base; it is either very
fleshy or almost membranous, nerveless, or one- two-,jD& three-nerved, with or with-
out red oblong dots (intercellular spaces roll of a ookmred juice), hairy, or almost
glabrous; the bract is equally variable in absolute and relative size.

An examination Of many hundred flowers having shown that no reliance aan be
placed on characters derived from them, and the shape of the leaves being mani-
festly of no value as a character, we have been compelled to conclude that the
'American and Indian plants are not distinct. Poirefc- had already anticipated us.
in this conclusion; and though some of the synonyms which he quotes are un-
doubtedly erroneous, it is evident that the Indian plant which he declared so posi-
tively to be the same with the Pareira and Caapeda of America, was the 0. con-
volvulacea of Willd. and "Wight and Araott, and that his mistake lay, not in this
conclusion as to the specimens before him, but in supposing that these produced the
Cocculns berries of commerce.

We have carefully compared a vary extensive series of specimens of this .species
from India, Africa, and America, and can with confidence declare that many Ajmeri-
can and African specimens arc identical with others from India. There are, no
doubt, one or two forms from America for which we have not been able to find exact
representatives among our Indian specimens; but their differences arc so trifling as
to be quite within the limits of variation in this, very variable Order,

It will be seen that we have not "quoted many synonyms of American authors.
We believe tfee number might have been very much extended, but the want of au-
thentic specimens has prevented us from enlarging the list. The characters dwelt
>ipon jfor tfeftc^eriminatioa ojf the numerous species described are notoriously variable
in all the species of thin genus, and we think it very doubtful if more than one scan-
dent species exists in America at all liable to be confounded with 'C. Pareira,

Oitsampelos Vogelii, Miers, from tropical West Africa, is perhaps distinct, the
shape of the drupe being, much more elongated. The male specimen, which Mr.
Miers considered to belong to tEat species, we have above referred' to C. Pareira.
& Togelii is also an American plant; at least specimens of C.fascieulata, Eentham,
wjttch is perhaps the same as C. denudvia> Miers, and is only a tomentose state of
C. andromorpha, DC., are'undietijignishaale from it.

Cocculut memdrawtceus, Wallich, is a curious dwewed state of C Pareira, in
which the branches are covered with multitudes of little pale-coloured, leaves. It is
not uncommon in shady jungles in the damper parts of the Himalaya,
